METHOD OF SPINNING OR TWISTING ARTIFICIAL FIBROUS MATERIAL.

SPECIFICATION iorming part of Letters Patent No. 716,138, dated December 16, 1902.

Application filed September 29, 1902. Serial No. 125,293. (No model.)

To all whom it may concern:

Be it known that il, ROBERT WILHELM STREHLENERT, civil engineer, a subject of the King of Sweden and Norway, residing at Djursholm, Sweden, have invented certain new and useful Improvements in Methods of Spinning or Twisting Artificial Fibrous Ma'- terial; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In spinning-machines for producing artificial fibrous material, (artificial silk and the like,) such as described, for instance, in the German Patents Nos. 96,208, 101,844, and 102,573, in which the spinning or twisting takes place by force of gravity and the cur rent of coagulating liquid is made use of for taking up the torn fibers, the apparatus can only be set to work either at starting or after an interruption-for instance, in consequence of the rupture of all fibers fed by the press,

when the fibers are caught hold of by handi. e., the textile fibers leaving the openings must be dipped down to the bottom of the means of a piece of wire or the like and caught hold of by means of a second wire introduced into the collecting-tube and drawn up to a spool on which the thread is wound. Since this operation is very tiresome and the quick collecting of the pressed-out fibers requires great practice in order not to losetoo great a quantity of the dissolved spinning material, the present invention has for its object an automatic collection of the fibers at the starting of spinning, as well as after a complete or partial interruption of the operation. The collection of the torn fibers and the further leading on of the bundle of fibers coming from the spinning-cone are permitted by the arrangement of a return-conduct which is destined to lead the'coagulating liquid between the spinning-cone and the collectingtube arranged as a prolongation of the same to the spinning-cone. By allowing the return-conduct to enter the inside of the spin- .the fibers.

hing-tube tangentially a rotation of the liquid is attained.

On the accompanying drawings, Figures 1 and 2 show the apparatus in longitudinal section and in plan.

The pressing-nozzle A is arranged in the spinning-cone B, which is destined for holding the coagulating liquid and which ends into the collecting-tube C for the spinning material or fibers H. The upper end of this tube C and the spinning-coneB are connected by a communicating-tube D. The bundle of fibers leaving the nozzle causes, by adhesion of the liquid on the fibers, a current, which sets'up a circulation by aid of the return-conduct. The tube D, which is intended to lead the coagulating liquid into the cone B, is preferably positioned'taugentially to the periphcry of the cone B. The coagulating liquid is introduced into the tube D by an elbow-pipe E, fixed to the tube and directed toward the cone B. By this arrangement the advantage is arrived at that in the cone B the current of liquid is greater and quicker, since the stream of liquid passing out from the pipe E carries with it fluid from the upper and widened part of the tube 0 and acts like an ejector, thereby rotating the liquid in the cone B, which at the same time has a continually-increasing velocity by reason of the funnel shape of this portion of the moving body of liquid; According to this arrangement it is not necessary to introduce a greater amount of new liquid than is necessary for the coagulation of However, the efiect of the amount of liquid serving to collect the torn fibers is in this case so great that this quantity is able to collect complete bundles of fibers, when the apparatusis set to operate from thebeginning on or after an interruption of the operation has taken place.

In order to prevent the bundle of fibers from slipping back with the current into the tube D, the mouth F of the same is covered, for instance, by a fine-wire net or the like. (Not shown.) Any superfluous coagulating liquid runs off through the overflow G.

What I claim, and desire to secure by Letters Patent, is-

1. The method of collecting artificial textile fibers, which consists in expressing the fibers into a body of coagulating liquid moving in the direction of the delivery of said fibers, substantially as described.

2. The method of collecting artificial textile fibers which consists in expressing the fibers into a body of coagulating liquid moving in the direction of the delivery of said fibers with gradually-increasing speed, substantially as described.

3. The method'of collecting artificial textile fibers, which consists in expressing the fibers into a rotating body of coagulating liquid moving in the direction of the delivery of the said fibers, for the purpose set forth.

4. The method of collecting and spinning artificial textile fibers, which consists in expressing the fibers iuto a rotating body of coagulating liquid moving in the direction of delivery of the fibers with gradually-increasing speed, for the purpose set forth.

5. The method of collecting and spinning artificial textile fibers, which consists in expressing the fibers into a vertical conical portion of a circulating body of coagulating liquid, and injecting tangentially at the upper portion of the conical body of liquid fresh quantities to replenish the depleted liquid, and simultaneously rotate the conical portion, substantially as and for the purpose set forth.

6. The method of collecting and spinning artificial textile fibers, which consists in expressing the fibers below the surface and into a vertical conical portion of a continuouslycirculating body of coagulating liquid, and injecting tangentially into the vertical portion of the liquid, above the point where the fibers are expressed, fresh liquid to replenish the depleted liquid and simultaneously rotate the conical portion, substantially as and for the purpose set forth.

7. The method of collecting and spinning artificial textile fibers, which consists in expressing the fibers below the surface and into a vertical conical portion of a triangular circuit of coagulating liquid moving in the direction of delivery of the fibers, causing the liquid returning to the vertical portion to enter tangentially, injecting fresh liquid into the returning portion and withdrawing dcpleted coagulating liquid where the fiber leaves the coagulating liquid, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
